what is the value of x

y intercept is 2, which shows while changing the jobs employees bring two customers.

A linear equation is in the form, y = mx + b where m is the rate of change (slope) and b is the y intercept (initial value of y).

The complete question is:

The graph displays the relationship between the length of time an employee works at a company and the number of the employee's monthly customers.

Time Employed (Month)

If the equation for the line of best fit is y = 4.5x + 2, which of the following can be used to interpret the y-intercept in context?

Employee training takes 2 months.

Employee training takes 4.5 months.

Employees are likely to bring 2 customers with them when changing jobs.

Employees are likely to bring 4.5 customers with them when changing jobs.

As, linear equation is

y = mx + b

Let y be the number of customers and x be the length of time.

Then, y = 4.5x + 2

As, y intercept is 2, which shows while changing the jobs employees bring two customers.

The transformation that can be used to show that ABCDE and its image are congruent is a 90° counterclockwise.

It should be noted that when we rotate a point through 90° counterclockwise, the mapping will be: (x, y) to (-y, x).

In this situation, it van be deduced that the x and y coordinates swapped positions. This illustrates a 90° counterclockwise rotation about the origin..

In this situation, since the rotation is a rigid motion, the two shapes are congruent.

The distances in feet covered in 4 steps, 6 steps, 12 steps, and 30 steps are 10 feet, 15 feet, 30 feet and 75 feet.

When you walk with a normal stride, the average distance covered in 2 steps is about 5 feet

From the question, we have:

Rate = 5 feet per 2 steps

This gives

Rate = 5/2 feet per step

So, we have:

Rate = 2.5 feet per step

The distance is then calculated as:

Distance = Rate * Steps

This gives

Distance = 2.5 * Steps

So, the distances in feet covered in 4 steps, 6 steps, 12 steps, and 30 steps are

Distance = 2.5 * 4 = 10 feet

Distance = 2.5 * 6 = 15 feet

Distance = 2.5 * 12 = 30 feet

Distance = 2.5 * 30 = 75 feet

Hence, the distances in feet covered in 4 steps, 6 steps, 12 steps, and 30 steps are 10 feet, 15 feet, 30 feet and 75 feet.

There are 210 different three-digit whole numbers that can be formed with the digits 2, 3, 4, 5, 6, 7, 8 if the digits cannot be repeated.

To calculate how many different three-digit whole numbers can be formed with the digits 2, 3, 4, 5, 6, 7, 8 if the digits cannot be repeated, we need to use the permutation formula.

The number of permutations of n objects taken r at a time, where order matters and objects cannot be repeated, is given by:

P(n,r) = n! / (n-r)!

In this case, we have 7 digits to choose from, and we want to form a three-digit number, so r = 3. Therefore, the number of different three-digit whole numbers that can be formed is:

P(7,3) = 7! / (7-3)! = 7! / 4! = 7 x 6 x 5 = 210

Each of these numbers will be unique, as we are not allowed to repeat any of the digits.

The height of the triangle will be;

⇒ 58.5 mm

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The base of the triangle = 4.7 mm

The area of triangle = 137.475 mm²

Now,

We know that;

⇒ The area of triangle = 1/2 × Base × Height

Substitute all the values, we get;

⇒ 137.475 = 1/2 × 4.7 × h

⇒ 137.475 = 2.35 × h

⇒ h = 137.475 / 2.35

⇒ h = 58.5 mm

Thus, The height of the triangle = 58.5 mm

Answer:

y=3x+8

Step-by-step explanation:

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

you find the slope by using this formula:

then we figure out it is 3

then graph to find the y-intercept which is 8

Answer:

y = 3x + 8

Step-by-step explanation:

Below is the image for the formula of the slope.

1. Subtract y values:
17 - 5 - 12
2. Subtract x values:
3 - (-1) = 4
3. Divide y/x
12 / 4 = 3
Therefore, the slope is 3.

Next, you need to find the y-intercept. This is our equation so far:
y = 3x + b
We can substitute any of the points given to us from the problem. I will use the first point: (-1, 5).

When substituting, you get:
5 = 3 ( -1 ) + b
5 = -3 + b
b = 8

Therefore, the equation is y = 3x + 8

Answer:

[tex]y^{-1} =\frac{1}{2} x-\frac{1}{2}[/tex]

Step-by-step explanation:

To find the inverse, you want to swap the inputs with the outputs, which is why you have the swapped domain and range between a function and its range.

So, given f(x)=2x+1, its inverse would give,

x=2y+1.

Solve for y,

2y=x-1 -> y=(x-1)/2 -> y=[tex]\frac{1}{2} x-\frac{1}{2}[/tex]

Therefore, [tex]y^{-1} =\frac{1}{2} x-\frac{1}{2}[/tex]

Using translation concepts, the equation for the graph is given as follows:

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, we have a cosine function(zero at pi/2, this is zero at the origin), shifted pi/2 units to the right and 1 unit up(as the standard amplitude is between -1 and 1, here is between 0 and 2).

We conclude that after 50 days, there will be 67 lily pads.

We know that the number increases by 25% every 10 days.

In 50 days we have 5 groups of 10 days, so there will be five increases of 25%.

We know that the initial number is 22 lily pads, if we apply five consecutive increases of the 25% we get:

N = 22*(1 + 25%/100)*...*(1 + 25%/100%)

( the factor (1 + 25%/100%) appears five times)

So we can rewrite:

N = 22*(1 + 25%/100%)⁵

N = 22*(1 + 0.25)⁵ = 67.1

Which can be rounded to the nearest whole number, which is 67.

So we conclude that after 50 days, there will be 67 lily pads.

⇒ f(-6) = 36 + 36 + 1

⇒ f(-6) = 73

x = -2

⇒ f(-2) = (-2)² - 6(-2) + 1
